Two-year test, NSA or will let its data center wash oiled bath

"Editor's note" Oil cold is not a new thing, as early as two years ago, Green revolution cooling through the oil cold into the eyes of everyone-the company's invention of the carnotjet cooling system compared with air-cooled, only a small energy consumption. It only takes percent of energy to cool down, which is much lower than your traditional server (50%-60%), and the world's most efficient data center, built by Google or Facebook, can drop that number to 10% to 20%, but it's not comparable to an oil-cooled system. Such messages, of course, are not missed by any Big data center player, including the NSA, which began testing green revolution cooling products two years ago.

The following is passage:

Security secret files are likely to be stored in a swimming service in the near future, and the NSA has been exploring the immersion cooling of its huge data center, soaking the servers in a liquid oil-like coolant. The agency says the technology has a huge advantage in reducing cooling costs:

On the construction of the NSA Utah State Bluffdale's Mega data center, the agency invested 1.5 billion of billions of dollars in the facility, which occupies 1 million flat feet. As a result, this cooling scheme is very attractive, which is why the agency will try Green Revolution cooling (headquartered in Austin) cooling program, but also reflects the NSA's cutting-edge technology to explore the initiative.

Liquid cooling is mainly used in HPC (high performance computing) because its high density configuration is difficult to manage with air cooling. As more applications and services demand higher density configurations, liquid cooling is becoming more and more of a concern, allowing data center players to re-examine the previous infrastructure to overcome the short panels on HPC and the facility.

Advantages of oil Cooling

In contrast to water, mineral oil not only does not conduct electricity, nor does it erode electronic originals, and as a thermal medium, mineral oil can basically be comparable to water. David prucnal, Advanced Computing Bae from the US Department of Defense, said in a quarterly study by the NSA that mineral oil had no specific heat of water and that he could carry 1000 times times as much heat compared to air.

In contrast to air, the greatest advantage of liquid cooling is that it can support higher computational densities. The NSA says that with no other special intervention, the immersion system can support 30-kilowatt per rack, while air cooling can only support 10-15 kw. The immersion cooling eliminates the fan, which is placed on a standard server, and the fan with control air flow consumes approximately 10% of the power of the server.

David also found that immersion cooling, while isolating air pollution, allowed all components of the server to remain at a constant temperature to reduce failure. David added: "Another advantage of immersion cooling is the mute, which, while seemingly innocuous, benefits the health of employees and caters to state regulations." There is, however, a potential obsession with the weight of a server and coolant rack that will reach 3300 pounds, about 1.6 tonnes. ”
